A stock doesn’t know you bought it.
It doesn’t know your research.
It doesn’t care how confident you are.
You can buy something at $100 because you think it’s worth $150, and watch it fall to $80 the next day.
That doesn’t automatically mean your thesis was wrong.
Markets don’t move on your schedule.
Sometimes the market needs weeks or months to recognize what you saw.
Sometimes the stock goes against you precisely because everyone else is looking at something different.
That’s where conviction matters.
But there’s an important difference between conviction and stubbornness.
Conviction means you have a thesis, you know why you own the trade, and you can explain what would prove you wrong.
Stubbornness means the stock keeps falling and you keep moving the goalposts.
If your thesis hasn’t changed, a red position isn’t automatically a broken thesis.
If the facts have changed, holding just because you don’t want to admit you’re wrong isn’t conviction.
The best traders aren’t right every time.
They know why they’re in the trade, what they’re waiting for, and exactly what would make them leave.
That’s how you let a good thesis run without turning it into a religion.
